That said, he'll be used out of the bullpen for at least the next few days.
The outfielder is batting .287 on the year with a homer and 13 RBI. Ross is batting .313 in May, however, over 48 at-bats.
If all goes well Reddick, who will avoid the disabled list with his wrist injury, will be sent out on an injury rehab assignment in the minors.
Ross (concussion) may not even need a minor league rehab assignment. He could be activated by Thursday if that is the case.
Harper was dealing with a bruised left knee. He enters the game Monday batting .171 (6 for 35) with two home runs and four RBI in 12 May contests.
Manager Joe Girardi said the Yankees intentionally kept him at a limited pitch count. They are not rushing him back.
"We'll talk about it," Girardi said. "Whatever it is we know he needs a couple days off."
Nova is on the 15-day disabled list with triceps inflammation. He suffered a setback when he was ready to return the last time and New York wants to play it safe.
The right-hander, who entered the year as the Blue Jays' fifth-best prospect, allowed four hits and one walk, while striking out six.
"Obviously, we're happy he's back pitching," Blue Jays assistant general manager Andrew Tinnish said. "I know he is, too. He's such a hard worker and dedicated young man. We expect he'll hit the ground running. He's been doing a lot of good things; he's in the right frame of mind. He'd been champing at the bit, and we were excited to get him back. Now that it's here, he just has to keep working."
The Blue Jays are in the process of converting the 2012 first-round pick into a starter.
"He's shown the ability to throw four pitches," Tinnish said. "I think there's a lot of quality on all four of them. He's not a tall guy, as we all know, but he's athletic, and he has a quick arm. When he commands his fastball, which he's been doing, and keeps it down in the zone, it makes his secondary stuff that much better."
That said, Youkilis is almost certainly at least a week away from returning for New York manager Joe Girardi.
"Is it possible we see him on this road trip? Maybe," Girardi said. "But I would expect to see him maybe a little bit the following week if everything goes OK."
Manager Ron Gardenhire said Doumit, who doesn't like to acknowledge pain, is a "little sore." He can be considered day-to-day for now.
Doumit has gone 13 for 51 (.255) in May thus far over 14 games with three homers and 10 RBI.
In 18 May games, Kipnis is batting .324 with two triples, six doubles, six home runs and 20 RBI.
